Crystal Palace manager Roy Hodgson is delighted to have secured the services of Michy Batshuayi.
The Belgian striker joins from Chelsea for a season long loan.
He could stay permanently, as there is an option to buy him outright within the loan.
Batshuayi managed six goals in 13 games for the Eagles during a previous loan spell, in the second half of the 2018-2019 season.
"I am very happy we have secured Michy on a season-long loan," manager Roy Hodgson said.
"He made a great impact at the club in his previous loan spell, albeit only five months long, displaying a goal scoring threat which we very much needed at that time and we are confident he will produce again.
"As a player who will help to convert our chances in to goals, Michy will be another valuable addition to the two new signings we have made this summer.
"It's another boost for the players and fans alike, and I'm sure everyone will join me in saying welcome back Michy."
